SPECIFICATION forming-part of Letters Patent No. 707,977, dated August 26, 1902. Application iiled December 7, 1901. Serial No. 84,7991. (No model.)

iro all whom it may concern: ing' substantially the same shape of the pan Beit known that I, THOMAS D. RADCLIFFE, shown in my other applications,above referred residing at Lawrence, in the county of Dougto,'and in the present case the pan (designated las and State ofKansas, haveinvented certain by A) is also bent up into the desired shape 55 5 new and useful Improvements in lVheeled from a single sheet-metal body comprising a Scrapers or Scoops, of which the following is bottom or scraper part a, the back a bent vera speciiication. tically, and the sides a?, the latter and the back My present invention, which relates tothat members being braced by angle-plates 1 and class of wheeled Scrapers having a dumping the end laps or ears 1, as best seen in Fig. 4. 6o Io pan or scoop, more especially seeks to pro- A A' designate what I term pan-lift vide certain improvements in the forms of brackets,onefor each sideof the pan.

K bracket A' extends above the upper edge of Ivly present invention seeks to provide a the pan and has its upper end formed witha simple, economical, and easily-manipulated bifurcated port 2, apertured to receivethe wheeled scraper in which the several parts pivot-bolts 3, as shown.A 'At a point just behave such coperative connection and combilow thebrackets A and at each side of the 7o zo nation, whereby the interlocking of the pan, panis secured a stay or foot-brace A3,.the purthe end, and the draft devices can be conpose of which will also be presentlyexplained. veniently effected and maintained in' such B designates a combined axle-supporting manner as to provide for a very effective digand pan-lifting frame which consists of the ging or scooping operation, and in which the pendent brackets b, each of which 'hasits 75 25 tilting devices are so disposed that the operaupper front edge apertured, as at b', toretor can easily and without much effort dump ceive the pivot-bolts 3, upon which thesaid the scoop to unload, and in which the several brackets b are pivotally mounted. As best parts can be quickly adjusted or returned t0 seen in Figs. 2, 3, and 5, the brackets b are their 4normal or transporting position. made of substantially triangular shape and 8o 3o With these and otherobjects in view,` rwhich with the pivoted end b and end 4a correlahereinafter willappear',myixy1vention consists tively so arranged that when the frame B is in certain novel details of construction and swung down to a horizontal position, as in peculiar. combination of parts, all of which'v Fig. 1, the end 4a will sweep into and engage will hereinafter be Afully described and specif-V with the foot-braces A3 and by reason thereof 85 35 ically pointed out in the appended claims, swing the pan forward and upward from the reference being had to the accompanying scraping position (shown in Fig. 3) to the cardrawings, in whichryingposition, (shown in Fig. 1,) as will here- Figure 1 is a perspectwe view of my iminafter be further explained. Each bracket proved wheeledscraper, the parts being in l) has ixedly formedtherewith a stub-axle 9o 4o their normal ortransporting position, the end- 5 5, which, it will be noticed, are disposed to gate being closed. Fig. 2 is a longitudinal the rear of the pivotal points of the said section thereof, the vparts being as in Fig. 1. brackets b, and on said axles are fitted the Fig. 3 is a View illustrating my invention, the wheels w w, as shown. To brace the frame parts thereof being adjusted to a loading B, the side brackets b' b thereof are joined by 95 4; position.l Fig. 4 is a View showing my imacross-rod6,and thesaid brackets are further proved wheeled scraper in a dumped position. braced by reason ofthe side extensions 19X bx Fig. isaperspective view of the vseveral parts of the frame extending at an angle and joinconstituting my improved wheeled scraper as ing with the handle member B', which has a detached from each other. forwardly-extending portion BX, upon which Ico 5o I n my present construction of wheeled is pivotally suspended the gravity-operating scraper the same includes a pan or scoop havor lifting latch B2, adapted to engage with the pan-catch A4, secured to the back of the pan. (See Fig. 2.)

A2 A2 designate pan, draft-hook, and endgate guide members, one of which is permanently secured to the front end of each side of the pan or scoop A, and the said members A2 each have a Vertical slot a12 in the upper end in a plane with the front edge ofthe scoop to receive and form guideways for the studs d, projected laterally from the side portions D3 D3 of the end-gate D, and the said members are also formed with horizontallydisposed forwardly-extending hooks d5 for engaging the latch members C C on the draftframe side arms C6 in the manner and for the purpose presently explained, and the said hooks 0,5 in the practical construction of my present wheeled scraper are disposed about six inches in advance of the slots am, the reason of which will also be hereinafterexplained.

The draft-frame in my present constructionincludesatransversely-extendingtongueframe metal brace-bar C, which is bolted on the inner end of the tongue T and to the converging portions of the side arms C, which connect with the said tongue T and have their inner ends turned up, as at c6, and apertured to pivotally hang on the stub-axles, as shown.

C5 designates supporting-arms ixedly secured at their lower end to the brace-bar C and extend rearwardly and upwardly at an acute angle to the side bars C6, their upper ends having pivot-bearings c5 to receive the upper ends of the side arms or hangers D/ of the end-gate D.

From the foregoing description, taken in connection with the accompanying drawings, it is thought the complete construction and the advantages of my invention will be readily understood by those skilled in the art to which it appertains. Its operation is simple and is best explained as follows: The several parts being in the position shown in Fig. 3, ready for scraping or digging, in which the gate is swung back, and the pan having been filled, the operator to bring the pan in position for transportation pulls the handle B and the frame B down in the direction indicated by arrow lO, and in this movement the lower ends of brackets b engage the footbraces A3, and in doing so they lift the pan and disengage the hooks a5 in engagement with latches c' c on the draft side arms C", and at the same time by reason of the studs d on the pan D engaging the sides of the slots a, the pan D will be held to close over the front end of the pan or scoop to hold the parts in position, as in Fig. Vl, to convey the load. The frame B when turned in the direction indicated has its hook B2 passed over the back of the scoop or pan to engage the pan-latch A, and by reason of such coperative adjustment of the several parts it is manifest that to dump the load it is only necessary to swing the handle B,with the frame B, back in the direction of the arrow 20, which movement will turn the parts over to the position shown in Fig. 4.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is

1. A wheeled scraper, comprising in combination, a pan, an end-gate closable over the front of the pan, a draft-frameupon which the gate is pivotally suspended, a pan-shifting and wheel-supporting frame, having stubaxles, and pivotally connected with the pan at a point in advance of its axles, and having a member for engaging the pan to lift it and move it forward, and interlocking devices controlled by the forward lift movement of the pan for effecting a closure of the endgate, as the pan is lifted and moved forward, as set forth.

2. A Wheeled scraper, comprisingin combination with a liftframe the supportingwheels, the vertically and forwardly movable pan, pivotally suspended from said frame, and the draft-frame pivotally hung on the axles; of the independentlymovableendgate pivotally suspended from the draftframe, and mechanism cooperatively connected with the pan and draft-frame controlled by the upward and forward swing of the pan for shifting said end-gate to its closure position, when the pan is elevated for transportation, as set forth.

3. The combination with the pan, a liftframe having side arms pivotally connected with the pan ata point in advance of the axles, said arms having the wheel-carrying axles projected therefrom a draft-frame pivotally joined with the axles, an independently-movable end-gate pivotally suspended from the said draf t-frame, latch-hooks on the pan, latches on the draft-frame, and means for moving the said hooks and pan to an interlocking position, substantially as shown and for the purposes described.

4. The combination with the frame B, including the side members b, and the stubaxles projected from said members; of the pan pivotally suspended from the members b at a point in advance of the axles, latchengaging hooks projected forwardly from the pan and secured thereto, and heel-braces on the pan in the path of the swing movement of the members l); of the draft-frame C pivotally secured to the axles, the end-gate D, pivotally suspended from the frame B, latches on the frame C for engaging the pan-hooks, and means for swinging the end-gate to its closed position as the pan is lifted and swung forward by the action of the frame B, substantially as shown and for the purposes described.
